Abstract

Carbon8 Systems Ltd. was formed in 2006 as spinout-company of the University of Greenwich. By using the Carbon8 process, industrial thermal residues are solidified and stabilised in a hardened pellet form that can be a direct substitute for natural aggregate e.g. for the production of concrete construction blocks. The aggregates produced were rigorously tested and given ‘end-of-waste’ designation by the Environment Agency. In early 2012, a bespoke commercial plant was commissioned at Brandon in Suffolk, UK, operated by Carbon8 Aggregates Ltd. In 2014, a second production line was added to the Brandon facility, increasing its capacity to 60,000 tonnes per year. The ACT-produced aggregate is carbon negative as it contains more imbibed carbon than is generated by its production. Consequently, the concrete construction blocks produced are also carbon negative, and are marketed under the name: ‘Carbon Buster’. Plans are at an advanced stage for the construction of a second production facility in the UK. This is scheduled to be operational by late 2015. The present work discusses the more recent developments of the commercial application of accelerated carbonation technology.
